Unstable call for the instance creating

Hi,We saw quite frequently an error message like below:"could not add instances: 500 - Internal server error. Please report this error to support@cognite.com and provide us with your request id: 4594f717-51c0-9708-86d3-5c5431f60cd1 and cluster name: westeurope-1"But when run it again it worked. The issue happens quite often(the number of instances in the request is close to 1000), could you have a check? Thanks. Regards,Xiaofeng

Filtering based on externalID

Hi,To apply a startWith filter on a property, we can do:prop_view = client.data_modeling.views.retrieve(('myspace', 'myview'))filters.Prefix(prop_view[0].as_id().as_property_ref("myPropertyName"),"xxx")This is working fine. However, as the externalId is not a property so the code below doesn’t work:filters.Prefix(prop_view[0].as_id().as_property_ref("externalId"),"xxx")and the error message is: “Invalid prefix filter with property reference [myspace, myview/94b12855a09cf4, externalId]. View myspace:myview/94b12855a09cf4 does not have property externalId.” Could you help find out how to apply a startWith filter on externalId in python sdk? Regards,Xiaofeng

Limit on adding instance API call

Hi,Currently we have a limit on the POST models/instances where we only allow to post 1000 instances at a time.This operation is currently limited to 1000 nodes and/or edges at a time.Normally between the instances there are dependencies so it is not very easy to split the request to multiple calls. Do you think it is possible to lift that limit to a big number, f.ex. 10000? Regards,Xiaofeng

Which API should be used to query all the linked instances(through edges) based on a root node

type SimulationModel { modelName: String! nodes: [SimNode]}type SimNode { modelName: String input: [Key]}type Key{ modelName: String unit: String}With the above sample schema, I am able to fetch all the SimNodes together with their Keys for a specified SimulationModel instance using the GraphQL:query MyQuery{ listSimulationModel(filter:{externalId: {eq : "00000000-0000-0000-0000-000000000000"}}){ items { externalId modelName nodes(first:100){ items{ externalId modelName input{ items{ externalId modelName unit } } } } } }}How to do do the same with the APIs, could you give an example? Not sure which API should be used(instances/list, instances/byids, instances/search, instances/query).

Could not create transformation for edges/relationships

It seems I can create transformations for types but there is no option to select a relationship when creating a transformation to a data model. Below it shows the “Target type and relationship” dropdown only has types but not relationships. Is there anything I missing?

Could not post nodes with Float properties if the value is 0 or negative

When adding a node instance with Float properties, it always gives an error “The value of property 'xxx' must be a 64 bit floating point number” if the value in the request body is 0 or negative number, but it works fine if the value is positive.Could you help take a look?

Can create an edge with any "type" through API call but could not see it in the UI

It seems I can create an edge with any type. In the code example below, the externalId of the “type” is set to “xxx” when calling POST Add edges, which should not exist. However, the edge was added successfully. Furthermore, I could not see any edges were created in the SimulationModel table, even the “externalId” was set to “SimulatonModelSimulator”.  { "instanceType": "edge", "space": "XiaofengTest", "externalId": "externalId:edge1", "type": { "space": "XiaofengTest", "externalId": "xxx" }, "startNode": { "space": "XiaofengTest", "externalId": "externalId:simulator1" }, "endNode": { "space": "XiaofengTest", "externalId": "externalId:simmodel1" } }

Could not download the demo data

It seems the link to download the demo data is not working in https://docs.cognite.com/cdf/data_modeling/upload_raw_dm. Once clicked the “the demo data” link, got an error message “This site can’t be reached”. Seems the dropbox link is broken. https://www.dropbox.com/s/o5o9eaewb9j57kt/FDM_Movie_data.zip?dl=1 Could you help have a check?
